The foregoing table indicates that owing to breaks in the recordsand their general short extent, only approximate results can beobtained. It is, however, believed that the results given are fairlyrepresentative of the evaporation in Maine, especially during thatpart of the year important in its relation to water storage. Duringthe winter months the relative evaporation at Lewis ton is probablylarger (as compared with that at the other stations) than during thesummer months, since the change in conditions at Lewiston is lessduring the winter than at the other places. Figure 3 is a curve showing the monthly evaporation at the fourstations and also a composite curve for Maine. It also shows the O Soldier Pond + Millinocket X Lewiston • IVlooselookmeguntlc. JAN.

As would be expected, the results show that evaporation fromwater surface in Maine is considerably less than for the vicinity ofBoston. The average annual evaporation from water surface in Maine asshown on figure 3 is about 26 inches, as compared with inchesat Boston. From May to September the Maine evaporation is inches, as compared with inches near Boston.

The results during the summer months arefairly representative of what may be expected, but the winter periodneeds further attention.
